SPECIFICATION forming part of Letters Patent No. 267,581, dated November14, 1882.

Application flled April 15, 1882. (No model.)

To all whom it may concern.-

Be it known that I, EZRA PEAK, of Westfield, in the county of Morrow andState of Ohio, have invented a new and useful Improvement inSulky-Plows, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in sulky-plows; anditconsistsin thepeculiar construction and arrangements of parts, as hereinafter morefully set forth.

Reference is to be had to the accompanying drawing, forming part of thisspecification, which represents my improved sulky-plow in perspectiveview.

A represents the wheels, and B the axle on which they are mounted, saidaxle being cranked between the wheels, said cranked part being extendedrearwardly a suitable distance in a horizontal plane, or thereabout, andhaving the frame 0 attached to said rear extension by eyebolts D,allowing the axle to swing up and down for raising the frame and theplow, of which E represents the beam.

F represents a yoke, having hearings on the axle at G, just inside ofthe wheels, and arched over the frame 0 in the vertical plane of theaxis of the wheels, or thereabout, to which yoke the axle B is connectedby the extensionrod H I, for raising or lowering the axle, according asthe yoke is shifted forward or back ward, for which said yoke isprovided with the foot-lever K, to be worked by the foot of the driver,who sits on the seat L, which is supported in a suitable position withrespect to said lever by the standard llLattached to frame OundertheyokeF. Forholdingthe yokein the required position, the suspension-rod Nis pivoted to the frame at O in advance'of the yoke and fitted through aslot in the yoke with a stop-pin, P, by which the yoke can be securedforward or backward to regulate the depth of the plow, said rod having aseries of holes, Q, for the different positions. It also has a notch,1t, in which to engage and hold the yoke when in the most forwardposition, for holding the plow high above the ground to pass over it.The heightto which the plow may be raised by the yoke F is also variableby the extension-rod H I, which hooks together by the hook-point S and aseries of holes, T.

The plow-beam E is bolted to the cross-bar V at the rear of the frame 0,which bar V is hinge-jointed to said frame at W and adjustably attachedto it by the notched latch X, by which it is supported higher or lower,as required, for shifting the plow as to its inclination to the verticalplane of the furrow, which is sometimes required, the plow workingbetter sometimes when perfectly upright and at others requiring to beset obliquely one way or the other, according to the nature of theground.

The foot-lever K is connected to the'yoke by a bar, Y, that is pivotedto said yoke, and has arms Z, carrying brakes (t, that are located overthe wheels well forward of the center, to be worked by the hand-lever J,extending backwardly from the yoke, so that the backthrust of the bodyof the driver is exerted in a direction backward from the seat whenlifting on said hand-lever, whereby the yoke will not swing forward, butthe brakes will be pressed on the wheels. When the driver transfers hisweight from the seat to the lever K, and the thrust is thereby mainlyforward of the yoke, the brakes will press on and be carried forward bythe wheels, and the yoke will swing forward and thus raise the plow. Thefront end of the plow-beam will be connected by clevis I) and chain withthe frame or tongue for drawing the plow. When the yoke is shiftedforward into the notch It of the bar N the frame O is raised up closeunder the yoke, so as'to lift the plow well above the ground.

' It will be seen that the arrangements of the adjusting contrivancesare simple and wellcalculated to be efficient and easily operated.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent The combination, in a sulky-plow, of an axlehaving a crank extending rearwardly, a yoke extending vertically overthe axle, a plowframc adj ustably suspended from the axle, and the yokeand plow adjustably suspended from the frame, substantially asdescribed, and for the purpose set forth.

EZRA PEAK.
